| Abstract: | Summary Anionomer prepolymers based on poly(propylene oxide) (PPG), 4,4 -dicyclohexylmethane diisocyanate (H12MDI) and dimethylol propionic acid (DMPA) were synthesized in bulk. The molecular weight of the prepolymers was determined by vapour pressure osmometry (VPO) and gel permeation chromatography (GPC). |
